No transfer record matches. ARIN's statistics show it reserved on 2026-09-30 and allocated (dated 2026-10-01) on 2026-10-02. The tracker saw this range removed from registration on 2026-03-24 (208.64.40.0/22), so it appears to have been issued again from ARIN's pool.

ARIN's statistics show it reserved on 2026-09-30 and allocated (dated 2026-10-01) on 2026-10-02. ARIN removed its own pool record for this range as part of issuing it: the same report adds 208.64.40.0-208.64.43.255. The issuance is explained on that line.

Hold estimate
Earliest estimated hold expiration 2026-05-23. Possible reissue candidate after this date; not confirmed available.
Removed from active registration. ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics. ARIN's statistics show it allocated (dated 2005-12-08) on 2026-03-23 and reserved on 2026-03-25. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed IPv4 for 60 days before reissuing them, so the earliest estimated hold expiration is 2026-05-23. This does not confirm availability.

ARIN's transfer log has no transfer of any part of this IPv4 range.
RDAP lookups
Not looked up. The tracker queries RDAP for changes as they're reported (on first sight, after 24 hours and after seven days); older changes aren't looked up because today's RDAP says nothing about the past.
